invention.

The ophthalmic mounting of the present invention comprises two rims 2connected by a spring bridge 4. Each rim is split at its point of 4junction with the bridge, as shown at 6, the split ends of the bridgebeing shown at 8 and It; The split ends 8 and H)- of each rim 2 arelocked. together andto' an" end of the bridge 4 by means of cooperatinglocking elements. As shown in Figs. 1 to 5,. 9 and 10, these-lockingelements may comprise twoadjacently disposed slots or other apertures I2and M in an end of the bridge 4 and two pairs 16 and I8 or I! and IQ oftongues or other projections on the split ends 8 and III of the rim. Thetwo" tongues I6 or I1, disposed opposite to each other, or unsp'acedalong the periphery of the rim, are disposed in the slot I2 and tightlyengagingithe walls thereof. The two similarly disposed tongues l8 or l9are similarly disposed 55 in the slot l4 and similarly engage thewallsthereof. Thetongues [6, H or l8, IQ of each pair are then bent awayfrom each other, in opposite directions transversely of the rim, andover against the bridge 4, as shown more particularly in Figs. 4 and 5.If desired, however, the pair 20 and 22 of tongues may be adjacentlydisposed on the bridge and the slots 24- and 2B in which they aredisposed on the rim and against the walls of which they tightly engage,as shown in Figs. 6 to 8. The bent-over portions of the tongues willthen be concealed, as shown at 28 in Fig. 8, instead of exposed, asshown in Figs. 4 and 5. It will be understood that the tongues 20 and 22may be disposed on the bridge 4 at right angles to the positionsillustrated, as in Fig. 10, so that the tongues 20 and 22, like thetongues I1 and I9, will be spaced from each other along the periphery ofthe rim. The tongues 20 and 22, like the tongues ll and I9, would thenbe bent away from each other in the opposite directions of curvature ofthe rim and over against the slotted member 2, instead of, as in Figs. 9and 10, against the slotted member 4.

As the ends of the bridge 4 are positioned against the exterior surfacesof the rims, it is desirable to round them over in cross section, asillustrated at 3|], to conform to the surfaces of the rims. Furthermore,as the split ends 8 and ll! of the rims 2 are permanently securedtogether when joined to the ends of the bridge 4, this would prevent theinsertion, in thelens-receiving groove 29, of glasses 3|, which areusually smoked or colored. The rims are, therefore, each provided with abendable or adjustable loop 32, originally occupying the dotted-linepositions illustrated at 33 in Fig. 1. After a glass 3| has beeninserted in the rim, the arms 34 and 36 of the loop 32' are closed inagainst each other, from the dotted-line positions to the full-linepositions shown at the left of Fig. 1, thereby closing the rim overagainst the glass 3'! in the rim. The loop 32 then serves the furtherfunction of a handle with which to manipulate the ophthalmic mounting.

In operation, the loops 32 are grasped between the fingers and thumbs ofones hands, and the rims 2 are moved away from each other, in oppositionto the spring action of the bridge 4. The ophthalmic mounting is thenpositioned in front of ones spectacles upon the face, with the glasses3| in front of the spectacle lenses. The spring bridge 4 is now allowedto actuate the rims 2 towards each other until the tongues 38 engageagainst the lower sides of the spectacle rims (not shown). Theophthalmicmounting will be held in place on the spectacles by the inherentresiliency of the spring bridge 4.

Other modifications will occur to persons skilled in the art and allsuch are considered to fall within the spirit and scope of theinvention, as defined in the appended claims.
